Supercars undertook barometric testing on Ford, Chevrolet and Toyota engines at its Brisbane engine shop from Saturday to Tuesday.<\/p>\n
A report was distributed to homologation teams on Wednesday night, with Supercars officials undertaking consultations in the paddock Thursday morning.<\/p>\n
It\u2019s understood the testing showed the Ford engine to be worst impacted by the barometric pressure at Bathurst, followed by the Chevrolet and then the Toyota.<\/p>\n
Speedcafe understands Ford teams are expected to receive a larger restrictor \u2013 52mm replacing 50mm \u2013 and a camshaft timing change.<\/p>\n
There will be no changes to the Chevrolet or Toyota.<\/p>\n
Supercars motorsport boss Tim Edwards confirmed the decision in a note sent to teams just under an hour before the start of Practice 1.<\/p>\n
The change will be in place for Bathurst only, with the Ford to revert to its previous specification for the Gold Coast 500.<\/p>\n
\u201cAs you\u2019re aware, Supercars have conducted Barometric engine testing over the last 12 months and recently completed a further test,\u201d it read.<\/p>\n
\u201cThe results of this test have been provided to the Homologation Teams following which consultation has taken place.<\/p>\n
\u201cThe testing has identified a power loss on the Ford at lower Barometric pressure and as such Supercars have approved a change of ESD developed by the Ford Homologation team to correct this for the Bathurst event only.<\/p>\n
\u201cNo change is required to either the GM or Toyota.\u201d<\/p>\n
It\u2019s expected that only one of the larger restrictors will be available to each Ford team for opening practice at 1:30pm local time.<\/p>\n","protected":false},"excerpt":{"rendered":"Triple Eight Race Engineering’s Ford Mustang during the Bathurst 12 Hour in February.
